To date, though, the evidence doesn’t support claims that extra vitamin C is helpful.” Thank you for your opinion. I’m interested as to why you believe Dr. Linus Pauling’s studies were “misguided.” Surely, scholars such as, Dr. Abram Hoffer, Dr. Max Gerson, Dr. Dan Rogers, Professor Ian Brighthope, and Dr. Dean Ornish, to name some, along with myself, would disagree.
Vitamin C For Kidney Function
The recommended dietary allowance for vitamin C is 90 milligrams (mg) for adult men and 75 mg for adult women.
Too much vitamin C can cause a buildup of oxalate in your body if you have chronic kidney disease. Dialysis can also deplete your blood of vitamin C. Research from 2012 found that people on dialysis can help increase their iron absorption by taking a low-dose vitamin C supplement of 60 to 100 mg.
Vitamin C And Kidney Cancer
Researchers have been exploring the potential of using high doses of vitamin C to treat cancer for decades.
However, high levels of vitamin C are not recommended for people with kidney cancer, as it could do more damage. Generally speaking, the vitamin C people get from food isn’t likely to be high enough to lead to kidney stones. However, vitamin C supplements (such as ascorbic acid tablets) could increase the risk.
A 2013 study on 23,355 men found that those who took vitamin C supplements experienced double the rate of kidney stones. To help minimize the risk of kidney stones, the National Institutes of Health recommends that adults consume no more than 2,000 mg of vitamin C per day. Understanding vitamin C Our bodies can’t make vitamin C. Instead, we get it from food or supplements.
